If you’re the type of person to avoid public restrooms at all costs, then you might have considered peeing in an ocean at some point. But is it actually okay for you to pee in an ocean? The answer is, yes! You can actually relieve yourself in the ocean.

It’s safe for the fish living in the system, as our urine has the same components as the ocean. In addition, our urine can also contribute to the ocean’s life cycle, so no fish will be harmed! While you can pee on the ocean, there are some locations that are an exception, as Refinery29 details:

Never pee near a coral reef. CNN reported that reefs near Mexico’s Quintana Roo province are suffering because of human waste spilled into the ocean by hotels tourists visit in the region. "There are a lot of nutrients going into the ground water caused by treated water from the hotels and municipal waste water treatment plants," environmentalist Paul Sanchez-Navarro told CNN. "They inject the water into the ground and that makes its way into the aquifer... We've found way too many nutrients — nitrates and phosphates — and that comes from human waste, mostly urine.”

Business Insider points out that small lakes are another place you shouldn’t tinkle. You might want to just get out of the water and find a toilet. TIME Magazine reported in 2012 that a lake in Germany had to close because of "an algae bloom that poisoned over 500 fish.” Some researchers blamed this on a ton of urine in the lake.
